CONTAINER.

Application filed February 2, 1927, Serial No. 165,485, and in GermanyFebruary 9, 1926.

The invention generally relates to containers and more particularly tothat class of containers in which are provided two chambers orcompartments each adapted to contain an ingredient or ingredients of aproduct, thus enclosing the whole of such prodnot while keeping theingredients. separated until ready for use.

In the preparation of paints for the market, for example, suchcontainers are particularly desirable because many paints, especiallybronze, aluminum and like metallic paints, if kept ready mixed for alength of time are apt to fade and deteriorate.

It is therefore the object of the invention toprovide a simple andeconomically constructed container in which is provided a mainreceptacle body and a partition member dividing that body into an upperchamber for holding the bronze, aluminum or other metallic powder, and alower chamber for holding the varnish or other liquid vehicle, the twoingredients being thus kept separated during the shelf or storageperiod. Further, the partition member has a knockout portion and a coveris rovided for the body which cover carries a nook-out plunger or pinthe upper end of which extends through the top of the cover and thelower end extends down through the upper chamber into close proximity tothe knock-out portion of the partition member so that s when it isdesired to use the paint it is only necessary to smartly strike theplunger to force its end into forceful contact with the knock-outportion to dislodge the same and open communication between the upperand lower chambers and permit proper mixing of the paint ingredients,this operation being possible without removal of the cover.

With the above and other objects in view that will hereinafter appear,the invention further resides in the novel details of construction,combination and arrangement of parts, all of which will be first fullyde- In carrying out the invention, according to one practicalarrangement, the container comprises an outer or main receptacle bodyclosed at its bottom in the usual manner and having a top flange 2 overwhich is mounted the flange 3 of the cup-like partition member 4 thewalls 5 of which may be slightly tapered to be smaller at the bottomthan at the top. The member 4 is open at its bottom as at 6, the openingbeing closed by a knock-out bottom 7 having a flange 8 to snugly fitwithin the opening 6 and normally form a hermetic seal separating thebody 1 into an upper powder chamber 9 and a lower varnish vehiclechamber 10.

A lid or cover 11 serves to close the container at its top and the saidcover is provided with an opening 12 in which is secured a frictionsleeve 13. A knock-out plunger or pin 14 is carried by the sleeve 13,the head extending above the sleeve and .its lower end extending belowthe sleeve into close proximity to the knock-out partition or bottom 7.To augment frictional contact of the pin 14 in the sleeve 13 the saidpin may be provided with a ribbed portion 16 for contacting with thesleeve.

It will be observed that the cover 11 is dished or provided with acentral depression. Thus when the pin 14 is in its normal position itshead 15 remains below the limits of said top and thus normal stacking ofthe containers in storage or shipment is'notv interferred with and thepossibility of inadvertent actuation of the plunger is rendered remote.

The container, of course, may be constructed in any manner conventionalin the related art and I do not wish to be limited to the preciseconstruction illustrated in Figures 1 and 2 of the drawing, as theconstruction may be varied within the scope of the appended-claims. Forexample, in Figure 3 of the drawing, I have shown a modified flangeconstruction which may be employed if desired. In this figure, I havealso shown the pin .14 equipped with a spiral-ribbed portion 16. In thisform the sleeve may be either smooth-bored or grooved as may be desiredto add to the frictional mounting of the plunger therein.

When the paint is required for use, the

plunger is smartlystruck 1n a downward direction, and such operationforces the bottom or knock-out portion 7, constituting the floor of theupper compartment 9, down into the lower compartment 10, allowing thepowder contained in the upper compartment to fall into the liquidvehicle 1n said lower compartment. This operation is performed with thecover 11 still in position and on removing the cover the mixed paint isaccessible for use.

By tapering the walls 5 of the partition member, means is not onlyprovided for facilitating the mounting of the bottom 7, but also a dripand brush wiping edge is provided surrounding the opening 6. Also an airspace is provided surrounding the lower end of the partition memberwhich allows expansion of the contents of the lower compartment withouttendency to force the bottom 7 upwardly which might flush with t e topedge of the cover.

result in'leakage from the upper compartment.

By positioning the plunger head 15 in the cover depression means is notonly provided to prevent inadvertent actuation of the plunger but alsofor indicating to the buy mg public that the container is intact and thepartition member unbroken. When in its normal osition the plunger beadtop is Thus, by noticing the position of the plunger head, a buyer canalways assure himself that the plunger is in its normal position.

From the foregoing description, taken in connection with the accompanyindrawing, it is thought the novel details 0 construction, the manner ofuse of the invention and the advantages thereof will be readily apparentto those familiar with the art to which it relates.

What I claim is:

A container of the class described comprismgl a receptacle body, a coverfor the body aving a central depression, a partition adapted to separatethe body into an upper and a lower compartment and including a knock-outportion, and a plunger PIO]8CtBd through and carried by the cover andhaving a striking head located within and operable in the depression ofthe cover and'a knock-out portion dislodging end projected into closeproximity with said knockout portion.

2. 'A container of the class described comprising a receptacle body, acover for the ody having a central depression, a partition adapte toseparate the body into an upper and a lower compartment and in c uding aknock-out portion, a lunger pro- 'ected through and carried by the coverand aving a striking head operable in the depression of the cover and aknock-out portion dislodging end projected -into close proximity w1thsaid knock-out portion, and a sleeve carried by the cover through whichthe plunger projects and in which it is held in tight frictionalengagement, said plunger being of a length that when the bottom of theplunger is in contact with said knock-out portion the head of' saidplunger will lie wholly within said central depression of the cover.

3. A container of the class described comprising a receptacle body, acover for the body having a central depression, a partition adapted toseparate the body into an upper and a lower compartment and includ-',

ing a knock-out portion, a plunger projected through and carried by thecover and having a striking head operable in. the depression of thecover and a knock-out portion dislodging end projected into closeproximity with said knock-out portion, a sleeve carried by the coverthrough which the plunger projects and in which it is held in tightfrictional engagement, said plunger having a ribbed portion. adapted to,engage in the sleeve to augment such frictional engagement, said plungerbeing of a length that when the ,bottom of the plunger is in contactwith said knock-out portion the head of said plunger will lie whollywithin said central depression of the cover.
